# Retrieve the SHA of the latest release for the linux/amd64 architecture.
# To accomplish this, we fetch all versions and identify the 5th version, which corresponds to the latest release with that specific architecture.

## NOTE: The SHA obtained in this step differs from the previous one, as it represents the branch commit SHA used for change verification.
